发布到 orion 让我 "Attribute must be a JSON object"

Question

我正在将此发送给 Orion：

curl --location --request POST 'http://xx.xx.xx.xx:1026/ngsi-ld/v1/entities/' \
--header 'link: <https://smartdatamodels.org/context.jsonld>; rel="http://www.w3.org/ns/json-ld#context"; type="application/ld+json"' \
--header 'Content-Type: application/json' \
--data-raw '{
    "id": "urn:ngsi-ld:Device:01",
    "type": "Device",
    "description": "L9A",
    "category": {
        "value": ["sensor"]
    },
    "serialNumber": {
        "value": "38479144"
    },
    "controlledProperty": {
        "value": ["Water Supply"]
    },
    "owner": {
        "value": ["Me"]
    },
    "location": {
        "type": "Point",
        "coordinates": [20.200416, 30.261837]
    }
}'

我明白了：

错误 400：错误请求

{
    "type": "https://uri.etsi.org/ngsi-ld/errors/BadRequestData",
    "title": "Attribute must be a JSON object",
    "detail": "description"
}

我通过 json 对象验证，它通过了。我做错了什么？

Answer 1

仔细查看您的错误消息，尤其是：

detail": "description"

那是不是 JSON 对象的属性的名称：

"description": "L9A"

如果将其更改为：

"description": {
  "type": "Property",
  "value": "L9A"
}

那部分应该没问题。

但是，您的所有属性似乎都缺少 type 成员。你需要将 "type": "Property" 添加到所有这些，除了“位置”是 GeoProperty:

"location": {
  "type": "GeoProperty",
  "value": {
    "type": "Point",
    "coordinates": [20.200416, 30.261837]
  }
}

也许花点时间阅读 NGSI-LD 规范？ https://www.etsi.org/deliver/etsi_gs/CIM/001_099/009/01.04.02_60/gs_CIM009v010402p.pdf
